利用正射影像立体像对的无人机测图系统
UAV Mapping System Using Orthoimage Stereo Image Pairs
摘要
Abstract
Using UAV image to map through traditional stereo image pair has to switch image pairs frequently,and mapping on the 3D real scene model made by the UAV images has to translate,scale and rotate the model frequently.Both mapping methods have low efficiency.Orthoimage stereo image pairs can seamlessly mosaic the left and right pieces of hundreds of stereo pairs to form a stereo image pair covering a large range.We developed a UAV mapping system based on orthoimage stereo image pairs.The operation mode was similar to the traditional stereo image pair,but avoided switching image pairs and improved the operation efficiency.We conducted 1∶2 000 mapping experiments in some projects.The results show that the plane accuracy of this system is about 0.2 m,and the elevation accuracy is between 0.2 and 0.4 m.关键词
